SCI 8: Plant Transport Systems

What does the xylem primarily transport in plants?

• Sugars and organic compounds

• Water and minerals

• Gases

• Proteins

What is the primary function of the phloem in plant transport?

• Transport of water

• Transport of minerals

• Transport of sugars and organic compounds

• Transport of oxygen

Which part of the plant absorbs water and essential mineral nutrients from the soil?

• Stem

• Leaf

• Root

• Flower

What process allows water to move through narrow channels and defy gravity?

• Photosynthesis

• Capillarity

• Transpiration

• Respiration

Which of the following is NOT a mineral nutrient required by plants for growth?

• Nitrogen

• Calcium

• Oxygen

• Magnesium

What role do the leaves play in the plant's transport system?

• Absorb minerals

• Transport water

• Perform photosynthesis and release oxygen

• Store starch

What is the primary purpose of transpiration in plants?

• To cool the plant

• To move nutrients through the phloem

• To release excess carbon dioxide

• To release excess water through stomata

What happens when the root system is damaged?

• Photosynthesis is enhanced

• Water and nutrient absorption is disrupted, leading to wilting

• Sugar production increases

• The plant begins to produce more oxygen

Which nutrient regulates water content in stomata and enzyme activation?

• Potassium

• Phosphorus

• Nitrogen

• Calcium

Which of these is a primary function of the stem in plant transport?

• Absorb sunlight

• Anchor the plant in the soil

• Transport water and nutrients between roots and leaves

• Perform gas exchange
